Abstract:
A method and/or apparatus for intelligent domain name server selection are provided. A mobile device may wirelessly receive one or more domain name server Internet Protocol (IP) addresses from a network serving agent during a call setup or a network registration. The mobile device then determines whether one or more of the received domain name server IP addresses is valid prior to attempting to contact a domain name server associated with one of the received domain name server IP addresses. A fallback sequence of valid domain name server IP addresses may be generated and provided (either individually or as a group) from a link layer to an application layer for domain name resolution. Received domain name server IP addresses that are geographically closer to a current location of the mobile device or its visited network may be given priority.
